Discuss the role of each of these factors in the causation of the COVID 19 pandemic: zoonotic virus origins immunologically naive population SARS-CoV-2 virulence factors affecting transmissibility evolution of immune resistant virus variants.
The omicron variant of SARS-CoV-2 has the amino acid substitution G339D in the spike protein on the virus surface. In cellular fluids at -pH 7 the wild type spike protein has a net negative charge. This substitution will make the spike protein: less negative absorb UV light more strongly at 280 nm more negative more hydrophobic
The COVID-19 pandemic coronavirus adhesin is the which binds to human receptors in the lungs. gp 41 binds nicotinic receptors on neuromuscular junctions gp 120 binds host CD4 receptors hemagglutini/H antigen binds sialic acid receptors S protein in envelope binds ACE2 receptors
Regular herpesvirus-mediated cold sores or genital sore flare-ups are caused by reinfection by the same herpesvirus strain reinfection by a closely related herpesvirus of a different strain copies of the herpesvirus genome permanently maintained in host cell cytoplasm copies of the herpesvirus genome permanently maintained in host nuclei
Choose all that apply to the Varicella- Zoster virus and infection with VZV A patient experiencing Shingles had a previous Chickenpox outbreak O The patient is generally older A mild immunosuppression event likely triggered reactivation Unlike chickenpox lesions, Zoster lesions are quite painful due to budding of virus from peripheral nerves The VZV infects and replicates in respiratory epithelial cells The VZV causes an initial viremia during the primary lytic infection O The latency period for VZV reactivation is usually days to months
Choose all the true statements regarding coronavirus proteins. Vaccine preventable diseases include COVID-19. For coronaviruses, it is more likely to find evolving mutations in the portion of the spike protein than the nucleocapsid protein. Mutations in the genetic code for the spike protein will produce 3D changes that are more likely to affect vaccine efficacy than changes to the nucleocapsid protein code. The nucleocapsid protein interacts with viral nucleic acid specifically whereas the spike protein interacts with the host protein non-specifically.
Which of the following coronaviruses causes the most serve illness in humans? O HCOV-NL63 O HCOV-HKU1 HCOV-OC43 SARS-COV all cause equally severe illnesses
During infection of a cell by Coronavirus, the N protein is: found on the outer surface of the virus particles synthesized on bound ribosomes on the rough ER synthesized in the cytosol on free ribosomes part of the RNA-dependent RNA polymerase required for binding of the virus particle to cells
Human Papillomaviruses are characterised by all of the following EXCEPT A genome of double-stranded circular DNA encoding around eight open reading frame These viruses are small naked and icosahedral They replicate in dividing cells and encodes three oncogenic proteins E5, E6 and E7 These viruses transmit primarily by nosocomial infection in hospitals HPV serotypes 14, 16, 18, 31, 45 are known to cause cervical cancer Rotarix is a vaccine indicated for the prevention of Rotavirus gastroenteritis caused by G1 and non-G1 types (G3, G4, and G9). Which of the following is NOT correct regards this vaccine? following immunisation, children may become irritable and experience diarrhoea ill infants or who born with SCID should not be immunized is live-attenuated vaccine derived from the G1P[8] rotavirus strain is prepared for IV administration is given in two doses None of the above Internationally, which clinical sample, at minimum, is used to diagnose COVID-19?

Which of the following is NOT true about the current coronavirus global pandemic (COVID- 19)? O Laboratory diagnosis of infection is based on polymerase chain reaction (PCR) testing of patient samples for RNA from the causative virus Nucleic acid vaccines to prevent COVID- 19 (and/or its most severe forms) are authorized for use in the US Caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Person-to-person transmission can occur through respiratory secretions (droplets and/or aerosols) None of the other four answers (All are true about COVID-19
What makes SARS-CoV-2 such a deadly virus? What structures allows it to be so efficient at spreading and infecting? How does it enter the body? Discuss the social aspects as well that made it a global pandemic.
Compare and contrast the role and types of viral mutations in 1918 IAV and SARS-C0V-2 in the respective pandemics, paying particular attention to: 1. causes of mutations 2. Key mutations responsible for generating highly pathogenic viral strain. 3. effects of mutated viral gene products on host immune system. 4. effects of newly emergent viral strain on virus spread worldwide.
